A thing is either alive or it isn’t; there is nothing that is almost alive. There is but the remotest possibility of the origin of life by spontaneous generation, and every likelihood that Arrhenius is right when he dares to claim that life is a cosmic phenomenon, something that drifts between the spheres, like light, and like light transiently descends upon those fit to receive it.

Every man has some forte something he can do better than he can do anything else. Many men, however, never find the job they are best fitted for. And often this is because they do not think enough. Too many men drift lazily into any job, suited or unsuited for them; and when they don’t get along well they blame everybody and everything except themselves.

For all these years you were merelyA smear of light through our telescopesOn the clearest, coldest night; a hintOf a glint, just a few pixels wideOn even your most perfectly-framed portraits.But now, now we see you!Swimming out of the dark - a greatStone shark, your star-tanned skin pittedAnd pocked, scarred after eons of driftingSilently through the endless ocean of space.Here on Earth our faces lit up as we sawYou clearly for the first time; eyes wideWith wonder we traced the strangely familiarGrooves raked across your sides, Wondering if Rosetta had doubled back to MarsAnd raced past Phobos by mistake –Then you were gone, falling back into the black,Not to be seen by human eyes again for a thousandBlue Moons or more. But we know you now,We know you; you’ll never be just a speck of light again.

For the most part we humans live with the false impression of security and a feeling of being at home in a seemingly trustworthy physical and human environment. But when the expected course of everyday life is interrupted, we are like shipwrecked people on a miserable plank in the open sea, having forgotten where they came from and not knowing whither they are drifting. But once we fully accept this, life becomes easier and there is no longer any disappointment.

In shades of black and blue the skies do bow as darkness falls the lights go out. Nature softly immersed in glee as all mankind drifts off to sleep. Water breathes a sigh of relief now aquatic creatures can do as they please. Animals whether large or small regain the natural instincts that man has fought. The moon shines bright he’s happy too people can’t over-ride his rules. Midnight calms the wounds of the world the break of dawn disperses new hope...

Looking at these stars suddenly dwarfed my own troubles and all the gravities of terrestrial life. I thought of their unfathomable distance, and the slow inevitable drift of their movements out of the unknown past into the unknown future.

Of course we have no means of staying back for any length of Time, any more than a savage or an animal has of staying six feet above the ground. But a civilized man is better off than the savage in this respect. He can go up against gravitation in a balloon, and why should he not hope that ultimately he may be able to stop or accelerate his drift along the Time-Dimension, or even turn about and travel the other way?

Our most trustworthy safeguard in making general statements on this question is imagination. If we can imagine the breaking of a law of physics then… it is in some degree an empirical law. With a purely rational law we could not conceive an alternative… This ultimate criterion serves as an anchor to keep us from drifting unduly in a perilous sea of thought.

Our world faces a crisis as yet unperceived by those possessing power to make great decisions for good or evil. The unleashed power of the atom has changed everything save our modes of thinking and we thus drift toward unparalleled catastrophe. We scientists who released this immense power have an overwhelming responsibility in this world life-and-death struggle to harness the atom for the benefit of mankind and not for humanity’s destruction. … We need two hundred thousand dollars at once for a nation-wide campaign to let people know that a new type of thinking is essential if mankind is to survive and move toward higher levels. This appeal is sent to you only after long consideration of the immense crisis we face. … We ask your help at this fateful moment as a sign that we scientists do not stand alone.

Extract from a telegram (24 May 1946) to “several hundred prominent Americans”, signed by Albert Einstein as Chairman, with other members, of the Emergency Committee of Atomic Scientists. It was also signed by the Federation of American Scientists.

The line separating investment and speculation, which is never bright and clear, becomes blurred still further when most market participants have recently enjoyed triumphs. Nothing sedates rationality like large doses of effortless money. After a heady experience of that kind, normally sensible people drift into behavior akin to that of Cinderella at the ball. They know that overstaying the festivities—that is, continuing to speculate in companies that have gigantic valuations relative to the cash they are likely to generate in the future—will eventually bring on pumpkins and mice. But they nevertheless hate to miss a single minute of what is one helluva party. Therefore, the giddy participants all plan to leave just seconds before midnight. There’s a problem, though: They are dancing in a room in which the clocks have no hands.

The proof given by Wright, that non-adaptive differentiation will occur in small populations owing to “drift,” or the chance fixation of some new mutation or recombination, is one of the most important results of mathematical analysis applied to the facts of neo-mendelism. It gives accident as well as adaptation a place in evolution, and at one stroke explains many facts which puzzled earlier selectionists, notably the much greater degree of divergence shown by island than mainland forms, by forms in isolated lakes than in continuous river-systems.

We must in imagination sweep off the drifted matter that clogs the surface of the ground; we must suppose all the covering of moss and heath and wood to be torn away from the sides of the mountains, and the green mantle that lies near their feet to be lifted up; we may then see the muscular integuments, and sinews, and bones of our mother Earth, and so judge of the part played by each of them during those old convulsive movements whereby her limbs were contorted and drawn up into their present posture.

Letter 2 to William Wordsworth. Quoted in the appendix to W. Wordsworth, A Complete Guide to the Lakes, Comprising Minute Direction for the Tourist, with Mr Wordsworth's Description of the Scenery of the County and Three Letters upon the Geology of the Lake District (1842), 15.

Winter opened its vaults last night, flinging fistfuls of crystalline diamonds into the darkening sky. Like white-tulled ballerinas dancing gracefully on heaven’s stage, silent stars stood entranced by their intricate beauty. Motionless, I watched each lacy gem drift softly by my upturned face, as winter’s icy hands guided them gently on their swirling lazy way, and blanketed the waiting earth in cold splendor. The shivering rustling of reeds, the restless fingers of the trees snapping in the frosty air, broke the silent stillness, as winter quietly pulled up its white coverlet over the sleepy earth.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) -- Carl Sagan
